Bill Beaty has created a neat way for magnets to be levitated. If you build it please be cautious since you could loose your hand if you aren’t careful. "While working on science museum exhibits in 1990 I came up with the above idea: it is known that a spinning metal disk will lift and fling a strong magnet. Therefore, metal rods with opposite spin will lift a magnet
I have seen a few of these waterfall displays before. But this water display has some very impressive patterns. I think if the room lights were dimmer the effect would be enhanced. These systems use many solenoids which are computer controlled to drip at the right time. Via: HackNMod

Trossen Robotics just completed their latest project contest, the Xr-B3 didn’t win but it is a very cool creation! "He is powered by an AVR ATMEGA324P micro controller on a custom board that I made. He is using an XBEE module to communicate with my PC (and eventually with other robots). Onboard sensory includes: 2 Sharp IR sensors (for wall following and obstacle detection), an SRF-05 sonar sensor and
Steve Norris from Norris Labs has created one of the most interesting clocks I have seen in a long time. This clock would make watching the time go by very enjoyable. "Stonehenge uses a CrustCrawler Smart Arm and a Parallax Propeller chip to display the current time. All the digits needed to display the time are located on cards positioned in a semi-circle around the left and right sides
The ArduGame packs all of the power into a small handheld unit that allows you to make your own simple games. The OLE display is responsible for much of the power since it can store many of the graphical images be stored on a memory card that it can read directly. The current game is a proof of concept that shows this game platform could be fun and flexible
Great job on the Hard Drive Clock and thanks for the mention about the clock that I built. 🙂 "The clock works by removing the top of the hard drive and cutting a slot into the platter. Then lights are mounted underneath and flashed as it spins. By timing it right you can create the illusion of clock hands, color bars or other designs. I have quite a few
